# `AshPhoenixGenApi.Resource.EffectiveField`
[🔗](https://github.com/ohhi-vn/ash_phoenix_gen_api/blob/v1.0.3/lib/ash_phoenix_gen_api/resource/effective_field.ex#L1)

A macro that generates common `effective_*` functions for configuration structs.

Both `ActionConfig` and `MfaConfig` share the same nil-fallback pattern for
resolving effective field values. This macro generates those functions to
avoid duplication.

## Usage

    defmodule MyConfig do
      use AshPhoenixGenApi.Resource.EffectiveField
      # ... struct and type definitions, unique functions, etc.
    end

## Generated Functions

The following `effective_*` functions are generated, each returning the
struct's field value when set, or the provided default when `nil`:

- `effective_timeout/2`
- `effective_response_type/2`
- `effective_request_info/2`
- `effective_check_permission/2`
- `effective_permission_callback/2`
- `effective_choose_node_mode/2`
- `effective_nodes/2`
- `effective_retry/2`
- `effective_version/2`

Additionally, these shared helper functions are generated:

- `has_explicit_arg_types?/1`
- `has_explicit_arg_orders?/1`
- `enabled?/1`
